What is the area of this composition shape enter your answer in the box 7 inches and 3 inches in 5 inches in 12 inches blank inches square
The area of the composite shape that is given in the image below = 40 in.².
How to Find the Area of a Composite Shape?In the diagram given below, the shape can be decomposed into a triangle and a rectangle, since it is composed of both shapes.
Thus:
The area of the composite shape = area of rectangle + area of triangle.
Area of the triangle = 1/2(b)(h)
base = 12 - 7 = 5 in.
height = 5 - 3 = 2 in.
Area of the given triangle = 1/2(5)(2)
Area = 5 in.²
Area of the given rectangle = (l)(w)
length = 7 in.
width = 5 in.
Area of the given rectangle = (7)(5) = 35 in.²
The area of the composite shape given = 35 + 5 = 40 in.².

An item is regularly priced at $55. It is on sale for 45% off the regular price.
An item is $55 before sale, and bought for 45 percent off the regular price. therefore the sale price of item is $30.25.
What is Markup and Markdown?Markup is the amount that will be increased in the original price of the considered thing.
Markdown is the amount that will be decreased from the original price of the considered thing.
Think of "up" and "down" as increasing and decreasing prices respectively.
Given that item is $55 before sale, and bought for 45 percent off the regular price.
WE have to do that as; 45% off $55 implies subtract 45% from $55
= 45/100 × 55 = $24.75
therefore the item bought at $55 - $24.75= $30.25.
Hence, the sale price of item is $30.25.

Maria bought 5 tickets for $20 each. Each ticket had a $2 fee. Write an expression that shows how much Maria paid for the tickets. plssss help will give 10 points :)
The expression to illustrate the information when Maria bought the tickets is C = (5 × $20) + ($2 × 5) and the total amount paid is $110.
How to illustrate the information?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. A mathematical expression shows the value of something by combining numbers, variables, and operators. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Mathematical operators like addition, subtraction, multiplication, and division are used to create expressions in writing. For instance, the mathematical equation for "4 added to 2" will be 2+4.
From the information, Maria bought 5 tickets for $20 each. Each ticket had a $2 fee.
The expression that can be used to illustrate this will be:
C = (5 × $20) + ($2 × 5)
where C = Total cost
C = $100 + $10
C = $110
Therefore the expression to illustrate the information when Maria bought the tickets is C = (5 × $20) + ($2 × 5) and the total amount paid is $110.

If the price of a business math text rose to $220 and this was 7% more than the original price, what was the original selling price? (Round to the nearest cent.)
Answer:
235.4
Step-by-step explanation:
7% more than 220 would be 235.4
First you would turn 7% as a decimal which would be .07. Then, you would multiply .07 times 220 which would give you 15.4. Lastly, you would add 15.4 plus 220 which would equal 235.4.
7%=.07
.07×220=15.4

When Rahul moved into a new house, he planted two trees in his backyard. At the time of planting, Tree A was 32 inches tall and Tree B was 20 inches tall. Each year thereafter, Tree A grew by 6 inches per year and Tree B grew by 9 inches per year. Let AA represent the height of Tree A tt years after being planted and let BB represent the height of Tree B tt years after being planted. Write an equation for each situation, in terms of t,t, and determine the number of years after the trees were planted when both trees have an equal height.
A= B=
Answer:
The equation to represent the growth of the trees is given by
AA=32+6t and BB=20+9t and both the trees will be of equal height after 3 years.
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
Equation is defined as the quality of being equal and is frequently represented by a mathematical statement with equal values on either side or by a problem requiring consideration of a number of factors.
Given that tree A is 32 inches tall and tree B is 20 inches tall.
Tree A grows 6 inches per year.
Length of the tree A after t years = 32 + 6t
Tree B grows 9 inches per year
Length of the tree B after t years = 20 + 9t
Now let us consider that both trees grows equal after a certain period of time.
If we equate both the expressions then we can form an equation to calculate the value of t.
∴ 32+6t = 20+9t
or, 6t - 9t = 20 - 32
or, -3t = -12
or, t = 4 years
The trees will be of equal length after 4 years.

and
[tex]p_{\mu,\nu}(x) = (x-z_1)^\mu (x-z_2)^\mu \cdots (x-z_\nu)^\mu[/tex]
The [tex]z_jz_k[/tex] terms occur in the coefficient of the [tex]x^{\mu\nu-2}[/tex] term, given by

A machine costing $214,200 with a four-year life and an estimated $19,000 salvage value is installed in Luther Company’s factory on January 1. The factory manager estimates the machine will produce 488,000 units of product during its life. It actually produces the following units: 123,200 in Year 1, 123,600 in Year 2, 120,900 in Year 3, 130,300 in Year 4. The total number of units produced by the end of Year 4 exceeds the original estimate—this difference was not predicted. (The machine cannot be depreciated below its estimated salvage value.)
The appropriate journal entries for year 4 depreciation is:
Dr. depreciation $52,210
Cr. Accumulated depreciation $52,210
What is depreciation?
Depreciation is the gradual systematic allocation of the cost of asset over its useful years, the fact that the machine in this case would be used for 4 years means that its initial cost needs to be allocated over the 4 years.
Depreciation(straight-line method)=(cost-salvage value)/useful life
Depreciation(straight-line method)=( $214,200-$19,000)/4=$48,800 per year
Depreciation rate per unit=($214,200-$19,000)/488000

In a survey on internet usage , it was found that out of a total of 27 people, 16 use ADSL lines, 15 use wireless internet and 3 use neither of the two . what is the probability that a person chosen at random uses both internet connections
The probability that a person chosen at random uses both internet connections is 1/9
Total number of people = 27
Number of people who use ADSL lines = 16
Number of people who use wireless internet = 15
Number of people who use neither of the two = 3
Let the number of people who use only ADSL lines and wireless internet be denoted by A and B respectively.
Then A + B + A∩B + 3 must be equal to 27
A + B + A∩B = 24
further, we can see that
(A + A∩B) = 16
B + 16 = 24
B = 8
Also, (B + A∩B) = 15
8+ A∩B = 15
A∩B = 7
Thus, the number of people who use both internet connections = 7
Now, P(A∩B) = 7/27
= 1/9
Hence, probability that a person chosen at random uses both internet connections is 1/9.

In baseball, a commonly used rate is earned run average (ERA). ERA is a rate of earned runs to a constant number n of innings. In 2020, the pitcher in Example 2 had an ERA of 2.70. Find the value of n.
The value of n which is a constant representing number of innings is equal to 50.
What is ERA or earned run average ?
Earned runs without the help of passed ball, are represented by the earned run average, which is the number of earned runs a pitcher allows per nine innings.
It is given that In 2020, the pitcher had an ERA of 2.70.
A rate of earned runs to a fixed number of innings, n, which is also known as ERA.
Let's check it.
To determine a pitcher's earned run average or (ERA), multiply the runs by nine, then divide it by the number of innings pitched.
The runs earned in 2020 is 15 , let's multiply it by 9.
So , we get 15 × 9 = 135.
Now , divide it by number of innings which is 50.
So , the value of ERA will be equal to : 135 ÷ 50 = 27 which is also given in the question.
Now we will calculate the value of n.
So ,
n = (9 × Earned runs) / ERA
or
n = ( 9 × 15 ) / 2.7
n = 135 / 2.7
n = 50 innings
Therefore , value of n which is a constant representing number of innings is 50.
